WebOct 26, 2024 · Any ADC has non-linearities and datasheets provide often the inaccuracy, e.g. how many bits are not reliable. It can be up to 2 bits per sample. A good (external) ADC reference can improve the accuracy, but you cannot overcome the ADC internal inaccuracy.

WebA test codelet below, designed to demonstrate the issue, repeatedly takes 12-bit readings from PC0 (ADC123_INP10) and PC1 (ADC123_INP11) with ADC1 or ADC3, using circular DMA. This code works with ADC1 flawlessly, but with ADC3, it stops reading, probably after the very first round.
